The Benefits and Effects of Purple Coneflower and the Best Month to Sow It
Today let's take a good look at the purple coneflower (Echinacea), a flowering plant that really catches the eye in the garden.
The purple coneflower, whose scientific name is Echinacea, is a perennial herbaceous plant in the genus Echinacea of the aster family. It is native to North America, and thanks to its beauty and practical value, it is widely grown around the world.
The flowers of the purple coneflower are simply superb. The blooms are large, reaching about 10cm in diameter. The most eye-catching part is its center, which forms a distinctive cone-shaped protrusion, hard and richly textured, mostly orange-yellow in color, just like a plump pine cone, which is also where its name comes from.
The purple coneflower also holds an important place in the medicinal field. It contains a variety of active compounds, such as polysaccharides, alkylamides and caffeic acid derivatives. These compounds give the purple coneflower its immune-regulating effects: they can stimulate the human immune system, strengthen the body's resistance, help prevent and ease illnesses such as colds and flu, and relieve the uncomfortable symptoms brought on by respiratory infections. At the same time, it also has a certain anti-inflammatory effect, and it has supportive therapeutic value for some inflammation-related conditions.
How to grow it
Growing from seed: the purple coneflower can be grown from seed. Spring sowing is usually in 3 - 4, and autumn sowing in 9 - 10. Scatter the seeds evenly over the surface of the soil, then gently cover them with a thin layer of soil about 0.5 - 1cm, then water thoroughly and keep the soil moist. At a suitable temperature, they will sprout in about 1 - 2weeks.
Care tips
Light: the purple coneflower is a sun-loving plant and likes plenty of sunlight, needing at least 6 - 8hours of sunlight a day. In a sunny environment the plants grow strong and the flowers are more vivid. But during the high heat of summer, a little shade can keep the flowers and leaves from getting scorched.
Watering: the purple coneflower is fairly drought-tolerant, but it still needs moderate moisture during the growing season. Generally, water 2 - 3times a week, adjusted according to the weather and how wet or dry the soil is. Avoid waterlogging so the roots do not rot.
Fertilising: in the early stages of growth, you can apply a dilute nitrogen fertiliser once every 1 - 2weeks to encourage stem and leaf growth; before the flowering season, increase phosphorus and potassium fertiliser, such as monopotassium phosphate, diluted to a 0.2% - 0.3%solution and sprayed once every 10 - 15days, which helps promote flower bud differentiation and increases the number and colour of the blooms.
Pest and disease control: common pests and diseases of the purple coneflower include root rot, powdery mildew and aphids. To prevent root rot, pay attention to soil drainage and avoid waterlogging; powdery mildew can be prevented by improving ventilation and lowering humidity, and when it appears you can spray agents such as triadimefon; aphids can be controlled with agents such as imidacloprid. In day-to-day care, promptly clearing away dead branches and fallen leaves and keeping the area around the plants clean and tidy can effectively reduce the occurrence of pests and diseases.
